Firms warned over definitive answer on gypsum wastes

摘要

Don't hold your breath for an airtight solution to the current unpopular 10 percent rule on sending gypsum-based wastes to landfill, is the message from researchers working for the Environment Agency. Work into the problem of sulphate bearing wastes is set to be written up in March but recycling and waste firms should not expect a definitive recommended level, says project coordinator Peter Braithwaite. "There are no conclusions yet and we cannot be confident of any percentage level of disposal being reached. It is a very complex matter. If 5 percent or even 196 there would still be hydrogen sulphide creation," he told MQR.
